Alcohol sobering up — New Mexico Permit Test
Alcohol sobering up on the New Mexico permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Your body gets rid of about one alcoholic drink per hour.
Four drinks take about four hours to leave your body, no matter how you feel.
Your body gets rid of one alcoholic drink per hour.
Coffee, fresh air, exercise or cold showers will not sober you up; time is the only thing that will.
Coffee may make you feel awake, but the alcohol is still in your blood and still slowing you.
Time is the only thing that will sober you up.
If you go where alcohol will be served, use a designated driver, public transportation or a cab.
Deciding how you get home before the first drink keeps a drunk brain from making that choice.
If you are going to a social situation where alcohol will be served, use a designated driver or use public transportation or a cab, if available.
On the test
About how long does your body take to get rid of 1 drink?
About 1 hour. Four drinks take about four hours to leave your body, no matter how you feel. New Mexico Driver Manual, p.29: “Your body gets rid of one alcoholic drink per hour.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
